Inkjet transparency film

Without taking the risk of wasting my money I'm asking the Forum whether they are any good. I have an hp printer and use hp paper and ink. It gives pretty good results which more or less satisfy me. I had the idea of presenting some appropriate pictures as transparencies on an illuminated screen for impact.
Can I expect 'impact' or just recognisable 'coloured pictures', doing it this way?
What's the general view? Is it worth my while buying a box or will I be disappointed?

Whilst not "Photo Quality" my experience of using transparancies has been quite favourable. Of course it depends upon the quality of the printer. I have used this method during training sessions and had no complaints from the delegates!
The transparencies I used (Cannot remember the correct title) were slightly rough on one side so the ink was readily absorbed!

Fair enough, thanks. Sounds like you are 'damning with faint praise' when you say "not Photo Quality". That's what I was after.
I guess, for loadsamoney, I can get what I want done commercially.
I did have some OHP transparency paper a long time ago and it gave very washed out images using my particular print settings. Things may be better now - but not that much better, it seems.

They are fine for powerpoint type bullet point presentations but photos are not that good on them. I used to use them until the Uni fitted data projectors in all the lecture halls (about five years after the infant school had them fitted in all the classrooms!).

I tried some as gobos in a theatre production and they looked brilliant projected to maybe 20 feet wide for 25 seconds before they melted.
